I have used the LTC4011 for battery charger application.
I have used the Figure 7. 3A NiMH Charger with Full PowerPath Control circuit.
It works great, but the only issue is LTC4011 CHRG LED not on and READY LED always On. even when the battery cell is fully discharged.
Please let me know if there are some solution for this issue.
The /CHRG LED is not on when the battery is being charged? All I can think of is that the LED is installed backward or there is some assembly error...if you remove the LED and measure the pin voltage, does it go low when charging?
As for the /READY LED, could this one be correct? The /READY signal is low under most cases. Refer to Table 1 for a breakdown.
The problem solved, it is a assembly problem.
Thanks a lot.
